Title: Braking power booster
Inventor: MATSUZAKI MIKIO
IPC: B60T13/12
Filed: 1978-11-01
Abstract: PURPOSE: To simplify the construction of a brake power booster which works even when the engine is interruped, by fitting a power piston through a valve operating rod and applying oil pressure to the piston in accordance with the shift of load.  
     CONSTITUTION: As a pedal is put on, a hydraulic brake is actuated, with a power piaton 4, master cylinder push rod 6 and piston 7 being interlocked. As the load is shifted, a piston 12 of hydraulic cylinder 11 is contracted and this hydraulic output is transmitted to a power piston cylinder 5, which generates a large boosting effect. A through hole 22 is open while the brake is not applied and no hydraulic output works on the piston 4 even if the piston 12 is contracted because of rugged road face.

Title: Magnetic bubble memory element
Inventor: AMATSU MASASHI
IPC: G11C11/14
Filed: 1984-07-02
Abstract: PURPOSE:To prevent the increase of the chip size of a magnetic bubble memory element by securing a double layer wiring of a gate conductor pattern and therefore rationalizing the winding of the gate conductor pattern. CONSTITUTION:The lower and upper gate conductor patterns 6 and 9 are laminated on a substrate 1 where a bubble garnet crystal 2 is formed together with spacers 3-5 and a ''Permalloy'' pattern 7. These patterns 6 and 9 are connected via a through-hole 8.

Title: Play restarting system for disk player
Inventor: YASUDA SHIGERU
IPC: G11B27/10
Filed: 1989-05-29
Abstract: PURPOSE:To easily restart playing from a picture at the time of interruption by executing position control so as to make the position of an information read point at the time of an interruption command coincident with the position of an information read point at a time point that a restart command is outputted and a rotation control servo is locked. CONSTITUTION:When a rotation control servo 6 and a position control servo 27 are turned off with responding to the interruption command and it is detected the restart command is outputted, the rotation control servo 6 and position control servo 27 are turned on. When the interruption command or restart command is generated, the information read point of a pickup 3 is moved and controlled so that the position of the information read point on the radius of a disk 2 at a time for the lock of the rotation control servo 6 can be almost equal with the position of the information read point on the radius of the disk 2 at a time for the execution of the interruption command. Thus, without requir ing the device of complicated configuration, the play can be restarted from the picture at the time of the interruption by simple operation.

Title: Radio communication system
Inventor: SATOU SADAICHI
IPC: H04W84/08
Filed: 1984-06-29
Abstract: PURPOSE:To save unnecessary power consumption by applying initial set and correction set to a timing generating circuit so as to transmit a connection control signal and make the reception timing thereby controlling intermittently power supply at reception standby without deteriorating the reception rate of the connection control signal. CONSTITUTION:When an initial timing set switch 12 is operated at a time t1, the timing of the timing signal between timing generating circits 11 and 21 is made coincident. When a communication request signal is supplied to a control section 6 from a press input terminal 8, a line connection control signal is transmitted from a signal transmission section 1 via an antenna 7 at a timing signal generating time t3. The 2nd radio equipment 60 synchronized with the 1st radio equipment 50 inputs the line connection control signal to a signal reception section 15 to execute the changeover from a control channel in use at present to a talking channel. On the other hand, the changeover from the control channel in use at present to the talking channel designated in the 2nd radio equipment 60 is executed in the 1st radio equipment 50. After the end of talking, the state is restored from the talking channel operating state into the control channel operating state and the power supply is intermitted.

Title: Uninterruptible path changeover system and control method
Inventor: URASHITA KEIICHI
IPC: H04L12/70
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To ensure transmission of proper data by eliminating the effects of a path switching timing onto main signal data in a system, where data are uninterruptibly transmitted by switching a plurality of the paths in response to failures. SOLUTION: After matching the phases of transmission frames received from two transmission lines by phase matching processing sections 40, 41, buffer memories 60, 61 delay the frames by a fixed period and give the delayed frames to selectors 70, 71. A frame monitor processing section 8 uses path alarm detection processing sections 50, 51 to monitor a path alarm in the transmission frame and gives a path switching instruction to the selectors 70, 71 when detecting the path alarm. In this case, the processing section 8 gives the path switching instruction in matching with the timing of an overhead part of the transmission frame, rather than of payload including main signal data. Thus, errors of the main signal data due to the path switching is prevented, and the reliability of path switching is improved.

Title: System for encoding and decoder
Inventor: WENG LIH-JYH
IPC: G06F3/06
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To obtain an encoding/decoding system for RAID-6 or a multi-track tape system by using a symbol stored on a redundant disk to correct an error of a data code word which can not be corrected by using an included error correction code(ECC) symbol. SOLUTION: An encoder 610 generates a redundant sector so as to encodes and records a corresponding sector from a data disk 612 on a redundant disk. The encoder 610 generates a redundant symbol by using a circuit 100r. The encoder 620 and an error correcting processor 630 correct an error of data stored on the data disk 612. The error is detected by using an ECC symbol stored on a data disk 612. The decoder 620 uses the (m+1) bit representation of an error-free (m)-bit sector and uses (m+1) zeros an error sector to decode the column. The error sector is therefore not read out in column encoding.

Abstract: PURPOSE:To reduce deformation by a rim flange and to prevent the generation of a rim cut by devising the arrangement of a carcass layer at a bead part. CONSTITUTION:The angle a made by the tangent T of a carcass layer at a point P and a straight line a-a' is taken at >=80 deg. provided the intersection of the inside of the carcass layer of the innermost layer and straight line a-a' is taken as P at the time when the straight line a-a' is drawn in the tire rotating shaft direction at the flange height (h) from the bead heel 6 equivalent to a rim diameter D at a bead part A. The deformation by a rim flange is thus reduced at the bead part and the generation of a rim cut can be prevented enough.

Title: Method of starting down hole pump
Inventor: KOIZUMI ATSUSHI
IPC: F03G4/00
Filed: 1983-07-25
Abstract: PURPOSE:To prevent an excessive flow rate from occurring at the starting of a deep well pump, by controlling the rotational frequency of a down hole pump based on a time function when the inside of a discharging pipe of the down hole pump becomes a gaseous phase. CONSTITUTION:At the starting of a down hole pump 5 that is used for pump up the well water in a deep well, it is made lower than the case where the lift at the prescribed rotational frequency No of the down hole pump 5 is zero. The speed of the motor of the down hole pump is variable, and the motor is started at a rotational frequency lower than the prescribed rotational frequency, and thereafter it will reach the rotational frequency of the operation point of the pump. Accordingly, abnormal lowering of the level of the well due to the excessive discharge at the starting of the pump and release of a gas dissolved in the water can be prevented.
